Without writing a GNUmakefile by hand, do any tools exist that understand Xcode projects and can build them directly against GNUstep, producing a Linux executable, thus simplifying (slightly) the work required to keep projects functional under Cocoa/Mac and GNUstep/Linux?
Basically, is there an xcodebuild style app for Linux?
I looked at pbtomake a few weeks ago but it seems to be a dead project.
Probably easier to build yourself a set of compilers and binutils that run on OS X but target linux.
